[arXiv] “RISTRETTO: a VLT XAO design to reach Proxima Cen b in the visible” N. Blind, M. Shinde, I. Dinis et al. — «RISTRETTO is the evolution of the original idea of coupling the VLT instruments SPHERE and ESPRESSO \cite{lovis_2016a}, aiming at High Dispersion Coronagraphy. RISTRETTO is a visitor instrument that should enable the characterization of the atmospheres of nearby exoplanets in reflected light, by using the technique…»

[arXiv] “nifty-ls: Fast and Accurate Lomb-Scargle Periodograms Using a Non-Uniform FFT” Lehman H. Garrison, Dan Foreman-Mackey, Yu-hsuan Shih et al. — «We present nifty-ls, a software package for fast and accurate evaluation of the Lomb-Scargle periodogram. nifty-ls leverages the fact that Lomb-Scargle can be computed using a non-uniform FFT (NUFFT), which we evaluate with the Flatiron Institute NUFFT package (finufft). This…»

[arXiv] “Using Neural Network Models to Estimate Stellar Ages from Lithium Equivalent Widths: An EAGLES Expansion” George Weaver, Robin D. Jeffries, Richard J. Jackson — «We present an Artificial Neural Network (ANN) model of photospheric lithium depletion in cool stars (3000 < Teff / K < 6500), producing estimates and probability distributions of age from Li I 6708A equivalent width (LiEW) and effective temperature data…»

[arXiv] “Nightside Clouds on Tidally-locked Terrestrial Planets Mimic Atmosphere-Free Scenarios” Diana Powell, Robin Wordsworth, Karin Öberg — «We investigate the impact of nightside cloud formation on the observable night-day contrast of tidally-locked terrestrial planet atmospheres. We demonstrate that, in the case where the planetary dayside is only 10s of Kelvin hotter than the planetary nightside, the presence of…»
